SPRING-SHACKLE.

SPECIFICATION forming part of Letters Patent No. 357,169, dated February8, 1887.

Application filed July 20,1886. Serial No. 208,561. (No model.)

our improvement are to facilitate 'the casting and construction ot' theshackle and adapt it to vibrate forward and backward and .also sidewiseand in other directions, while all the rattling of the parts isprevented. Ve accomplish these objects by the constructionillustrated-in the accompanying drawings, in which- Figure 1representsin perspective a wagonbody and one of its axles and springswith shackles constructed in accordance with our invention. Fig. 2represents'on a larger scale,

, bdv and A its metallic supports secured preferably to the under sidethereof.

B represents one of the axles, to which are secured,by clips b,springsC, preferably formed of superposed leaves bent in the form of segments,the longest leaf having one end coiled to receive th rough the loop thusformed a bolt, c, that passes also through the upper ends of linksd,whi1e the lower ends of said links receive a bolt, c', that passesthrough a rectangular block, E. This block is provided with trnnnions e,that are received in perforations made in the two upper jaws, f, of alink, F. This link has at its lower end two similar jaws, f', to receivea rectangular block, E',

- provided also with'trunnions e', that enter the perforations in thelower jaws, f', and through the perforation in the block E is passed thelower end of the wagon-supports A', a nut,

a', on the end of the latter completing their connection with theshackle, composed of the links F and blocks E and E To facilitate theconnection of these blocks with the links F, the latter consist of twoparts secured to- ,gether face to facein themiddle of theirlengthl by arivet, f, and each has said middleportion, between the single jaw at-each end, twisted a quarter of a turn, so that while the axis ofthetrnnnions of the upper block, E, is

`transverse bolts c, whilethe opposite end rests either upon the lowerjaws or upon the wagonbody supports A and their nuts a', and preventsthe loosening of said nut. A coiled spring, g, may also be used, asshown in Fig. l, between the wagon-body and its axle, for nearly thesame purpose.

Having now fully described our invention, we claiml. In combination withthe supports of a wagon-body, its spring and links d, a shackleconsisting of two links, F, secured together face to face to form jawsat each end, having perforations, with perforated blocks havingtrnnnions to enter the perforations in the jaws of the links,substantially as described.

2. The combination of a wagon-spring and its shackle, consisting of twolinks secured together in the middle of the length to form jaws at eachend, with perforated blocks between said jaws, and a coiled springsurrounding the shackle, substantially as and for the purposeldescribed.

In testimony whereof we affix our signatures in presence of twowitnesses.
